According to my own experience, gambling in some games could gives you some lessons that life cannot during years.
Let us take as an example, the decrease of the greed in my attitude and how to control it that I learned thanks to the gambling.
Almost all gamblers get lesson from gambling, but some gamblers get good lesson and some gamblers get bad lesson from gambling, even they take the hardest life because of gambling. But you are lucky ones, that's why you get a good lesson and have good effect in your life. Eventually i see a luckiest gambler who said that gambling learn him the good lesson of life.
